Euro Fuel Line Problem

I picked up a set of NOS euro fuel lines a couple of months ago off of ebay. Had them installed today and my mechanic had all sorts of trouble getting one of them to seat correctly. Car just wouldn't run worth a crap and was leaking fuel at the injector connection.

He ended up swapping that one line our the original US unit. Turned it over and the car ran great. My concern now is that there is a possibility that one cylinder is now getting possibly less or a slightly delayed shot of fuel compared to the others that are running the larger euro lines. Am I just overly paranoid or could this be a real issue?

Thanks

No delay. C in CIS stands for continous. It doesn't squirt in shots....it's pouring all the time, so pipe length is quite unimportant.

That much I figured however my concern is the volume of fuel traveling through the single narrow US fuel line versus the other 5 larger RoW lines.

What is the difference in ID between Euro and US fuel lines? Are they actually different or an old wives tale?
If the ID is significantly smaller in the US version it stands to reason that the presure would be greater for a given volume than that of the Euro lines. Can't imagine that it would be significant.

Brian - I didn't measure but can tomorrow when I get back into the shop.

BTW... the new exhaust sounds great. May be a bit too quite for my tastes but the tone is really nice. Thanks for all the custom work. I am going to take some pics tomorrow and post on the original post.

I am going to guess that there may be a problem at high bhp figures. Up to 200bhp should be fine.

I would try to get it repaired/altered so you can fit it. In the mean time no boost.
